I've done extensive research on this subject, for coronavirus purposes N95 is equivalent to FFP3. The most important aspect is having head bands (as opposed to ear loops) to secure a tight fit. N95 typically have head bands. FFP2/KN95 (filtering equivalent to N95) typically don't, which is why FFP3 are sometimes preferred. There are also regulatory reasons to use FFP3. 3M also manufactures FFP3 masks. Not sure if they sell them outside EU though. https://www.amazon.co.uk/3M-9330-Aura-Unvalved-Respirator/dp/B00VAT74NG https://www.amazon.co.uk/3M-9330-Aura-Unvalved-Respirator/dp...
